What is the role and structure of minority languages in Swiss SMS and what can be the consequences of SMS communication on a diglossia situation? The project will analyze phenomena of language choice and uses in three kinds of contact situations, namely Italian and dialect in the cantons Ticino and Grisons, Romansh and German in Grisons, and Italian and German outside the Italian-speaking territory. The starting point is the observation that minority languages and dialects are more often used in SMS than it is the case in other written communication forms and the main hypothesis is that these new written forms of communication will alter the sociological status and structural make-up of minority languages.
